In this paper, we study attrition in a household panel survey, where in the firstwave those with a matched landline number were surveyed by telephone, whilethose without received a face-to-face visit. In the second wave, the face-to-facemode was dropped. We find among the first wave face-to-face households a highlikelihood to attrite due to "no contact" rather than due to "cannot be tracked"or "refusal". Socio-demographic characteristics have the expected effects. Forexample households with young children, with a short-term residence permit,or one-person households cannot be tracked, while those with a face-to-facevisit in the first wave, or foreigners with a mother tongue that is not offered inthe survey refuse more often. More first wave calls and contacts are associatedwith all reasons to attrite, in particular with refusal. Based on the findings, wegive recommendations to tailor fieldwork to decrease attrition.
